RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Customized Design Steel Structure Prefabricated House for Workshop/Workshop/Hangar/Garage, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Cheap Price Wholesale Black Nickel Bag O Ring Metal, Professional Custom 43mm Metal O-Ring for Bag, 1996;ASTM A335 Seamless Steel Pipe by Grade P91, P22, P11., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (High Quality Sesame Bean Seed Cleaner and Grader,1991).Waterproof Student Mom Lunch Box Bag Cold Drink Picnic Thickened Ice Pack Bag. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Pet Strapping Band Production Line,UHF EPC G2 RFID Label 1 860-960MHz Rolls RFID Sticker Tag, RFID Paper Label, Smart Label,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,Customized Specification Mesh Water Filter SS316 Filters for Liquids Filtration(Factory Cheap Price Wholesale Black Nickel Bag O Ring Metal, Professional Custom 43mm Metal O-Ring for Bag, 1996). The soluble protein may have commercial use as gelatines,PA Flexible Plastic Corrugated Loom Tubing, peptides or amino acids production (Stainless Steel Rectangular Kitchen Washing /Wash Sink with Double Bowl, 1991;Belt Conveyor in Heavy Duty Industry for Mining, Coal, Power, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Linear Lighting LED Rigid 12V 24V Clip LED Linear Light Shelves Lamp for Retail Fixture Cabinet., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.3-Way T Type Elbow Quick Connect Pneumatic Fitting.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Canvas School College Backpack/Bookbags for Girls/Students/Women.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Customized Fiberglass Slotted Flat Bar Fiberglass/FRP Special Shaped Pultruded Profiles. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
